Summary0002049: evaling broken code (still) causes unhandled exception in PHP 7.4
Description

This issue is directly related https://bugs.xdebug.org/view.php?id=1993 .
The fix works well on PHP 8, but not on PHP 7.4 and before.
Specifically placing the text "namespace" in VS Code watch - thus executing eval namespace breaks following step operation.

Steps To Reproduce

Crate file

<?php

xdebug_break();
echo "1";
echo "2";

Stop execution on breakpoint and run eval. Step next and it sould

eval -i 17 -- bmFtZXNwYWNl
<?xml version="1.0" encoding="iso-8859-1"?><response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="https://xdebug.org/dbgp/xdebug" command="eval" transaction_id="17" status="break" reason="ok"><error code="206"><message><![CDATA[error evaluating code]]></message></error></response>

step_over -i 21
<?xml version="1.0" encoding="iso-8859-1"?><response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="https://xdebug.org/dbgp/xdebug" command="step_over" transaction_id="21" status="stopping" reason="ok"></response>

I can't reproduce this with the information provided: https://github.com/xdebug/xdebug/pull/812 — Can you provide the full xdebug log and script that you use please?

Here is the, code, xd2.log that show stepping through it without executing evaluate, and xd3.log that adds the eval command in the middle. See the lineno in stack, how it jumps to 0.

Fixed for Xdebug 3.1.3. I've removed the version define check altogether, as it was needed for PHP 7.2 and up, but also had to adjust the patch due to a new compiler warning.
